xwayland: move glamor specific routines

Browse Source 
Functions such as:

  xwl_glamor_egl_supports_device_probing()
  xwl_glamor_egl_get_devices()
  xwl_glamor_egl_device_has_egl_extensions()

Are of no use outside of EGLStream support, move them to the relevant
source file.

Similarly, the other glamor functions such as:

  xwl_glamor_init()
  xwl_screen_set_drm_interface()
  xwl_screen_set_dmabuf_interface()
  xwl_glamor_pixmap_get_wl_buffer()
  xwl_glamor_init_wl_registry()
  xwl_glamor_post_damage()
  xwl_glamor_allow_commits()
  xwl_glamor_egl_make_current()

Are useless without glamor support enabled, move those within a
a "#ifdef XWL_HAS_GLAMOR" in xwayland.h
